To all whom it may concern Be it known that I, Anrmm L. Russel-.11, a citizen" of the United States, residing at Hyde Park, in'the county ofNorfolk and State of Massachusetts, have invented certaip Improvements in Apparatus for Use in the Manufacture of Boots and Shoes, of which the following description, in connectlon with the accompanying drawings, is a speci fication, like reference characters. on the drawings indicating like parts in the several figures.

' This invention relates to the manufacture of shoes and while there are disclosed in this specification and drawings improvements in: methods of making shoes, improve-- ments in shoes and improvements in toe and turn shoes are provided with .upstandto provide means with w subjects binders which respectively constitute the matter of" divisional applications Ser; Nos. 711,648, 802,157 and 711,64?,,the invention herein to be protected relates more particularly to. novel apparatus for use in the operations of lasting and temporarily securing shoe uppers. 4 e

A present general practice is to overwork the upper into lasted position about the toe end of the last by wipers that have acting edges shaped to embrace the toe portion of the shoe and lay the upper over the margin of the innersole. The innersoles of welt ing lips or other formations that present a shoulder against which the upper 18 lasted. A binder of wire or other continuous-.material is employedto secure the 'upper in lasted position by anchoring it at one end and drawing it tightly about the upper around the'toe to bind 1t against the shoul- -der of the innersole after' which it is anchored under tension:

An object of the present invention is to bind the toe without the use of anchor tacks and a further object is to improve the binding of .theupper, whichtrequently slips to some extent under the bindin wire. 1

' Other objects of'the pres'en invention are hich to improve the shaping of the upper to the last and the in; nersole and particularly the shaping of that portion of the upper which overlies'the margin of theshoe bottom, to increase the per-' manence of such shape for producin the shoe claimed in application SerIN'o. 8 ,157,

.in the claims.

and to provide improved means for apply mg binders and particularly for utilizing the bmder wh1 ch terms the subjectmatter of apphcatlon Ser. No. 711,647.

The novelfeatures of this invention, which include certain combinations of parts and more important details of construction, will be better understood in connection with the following description of the apparatus and the manner m 'whlch it is contemplated it shall he used, and will then l e-pointed out shoe having the upper secured hythe binder of this invention.

-The machine comprises the usual shoe V supports at the heel 2 and toe 3 with heel lastmg wipers 4 and toe wipers h. The lat ter are mounted on a vertically movable head 8 that is lifted by' a foot treadle 10*and the wipers are opened and closed with a simultaneous longitudinal movement by cams 12 andlink connections with a hand lever 15. parts may all be .as in the .machine shown and described in United States 'Letters Patent No. 1,018,477 granted'Feb.

27, 19 12 on application of MatthiasBrock. In accordance with this present invention the toe wiper cams also support for movement toward and 'from operative relationto the shoe auxiliary devices 21 herein termed end rubbers that are pivoted onthe cams and have yielding edge members '20. These have a movement longitudinally of the shoe edge in rubbing contact the sides of the'toe. r In ddition to their movement with the toe wipers the endqrubbers '21 have arubbing movement directed toward the heel in contact with-the upper, which creases the upper into the an guided in the cover plate of the wiper carrying head and is actuated by a lever 26 and a link connection to a lever 22 thatis pivoted on-thesame fulcrum as thewipe'r le between-the lip and the feather of a we t innersole. To end. the end rubbers each have a crank arm 23 connected by an equalizer 24 ton. slide that'is' operating lever 15 and overlies that lever. Lever 22 is slightly resilient and has a handle 27 and a stud by which it can be engaged with one or another of a segmental row of holes in an enlargement of lever 15' whereby lever 22 and the end rubbers may" be actuated with the wiper operating lever.

The handle 27 also provides means 'fori"effecting independent turning movement of" the end rubbers. The end rubbers are ee centrically pivoted so that this independent movement by the handle 27 jclosestheir yielding'contact members 20 further, or with lncreased pressure, over the shoe bottom as well as turning them in rubbing contact with the stock. It will be noted also that the normal movement of the'end rubbers 21 with the wipers is accompanied by a rotation about their eccentric? axis which advances or retracts them more rapidly than the wipers are moved. Thus the end rubbers normally stand back of "the wiper edges, in an out-of-the-way position, where they may not contact with the sides of the shoe in the upward movement of the wipers along the sides of the shoe when the head is raised by the treadle 10. When the wipers advance to lay the upper over the feather of the innersole the end rubbers advance faster than the wipers do, because of turning about their eccentric pivots, and so come-into yielding pressing and rubbing contact with the upper against the lip of the innersole to crease it into the angle between the lip and the feather. The end rubbers will be arrangedto act on the shoe in the region of the tip seam where the upper materials are especially bulky and this creasing action is particularly desirable in order to obtain a uniform position and appearance of the-inseam and the welt in the welted -shoe. This action of the end rubbersalso efiects aspecialtightening of the upper-in the region "of V the tip seam and back of the endsof the wipers where it serves-to improve the last ing of the shoe. When the wipers are partially backed away from the overwiped upper to insert the hinder the end rubbers are retracted faster and farther than the wipers so that abundant space is made for placing low-the plate 7 over which thewipers and end rubbers stand in their retracted position, said flames being particularly located rendered tacky by heat- "After the toepor- ,tion of the upper has been o 'erwiped to heat the end! rubbers.;*Any other heating means may of course be substituted.

The binderadv-antageously employed is a fabric. or paper strip 30 with adhesive on the back thatpreferably is of a quality to be against the shoulder 32 of the innersole the wipers are backed away from the upstanding flange 3% of the upper far enough to allow thestrip'of binding material to be dropped edgewise between the wiper edges and the upper with'its coated back toward the upper which has been warmed by previous contact with the heated wipers. The so wipersare now again advanced to press the p binder against the flange 34, and particularly against the base of the flange, and to heat the binder to render the adhesive tacky or adherent to the upper. The end rubbers are then actuated to rub the two ends of the binder rearwardly to tighten it and to make .it stick firmly to the upper.

If desired, the end rubbers only might be heated and to such a degree that by being 9) merely rubbed once over the end portions of the binder without standingin contact therewith they would cause it to adhere to the upper and become anchored while the unheated wipers held the body portion of the binder in binding relation to the upper about the toe. Advantageous results will, however, be obtained by heating the wipers to an extent. tocause them toheat the surface-of the upper engaged by them and to adapt them tov 10.) soften an adhesive coated binder to cause it to stick to the upper for holding it in lasted position. Preferably the wipers are so heated that not only do they act more effectively than cold wipers for surface smoothing the upper and for molding it to the desired shape of the last and the innersole, but they are heated to'a degree suflicient for shrinking the upper materials to the last. The upper does not require-to be bound with the same security after having been overworked,

"molded and shrunk by the /use of heated wipers. When heated wipers are used they will pre'ferably. be partially backed off to allow the binder adhesive to set while they hold the upper, the heel seat lasting being conveniently carried on during this time. I have shownthe parts of'the apparatus as operated' by hand but the wipers and end rubbers may beactuated in proper time, relation autoinatijca y and the binder may be placed automatica y,when the wipers are backed off to receive it, with or without previously warming the. binder'to render the adhesive sticky before the binder is placed. An apparatus embodying this feature will be separately claimed in another application.

. The advantage which is obtained from the use of heated wipers in shrinking'the. fringe of the upper after it has been folded in over amass? the edge of the last bottom is of special importance. The shrinking of this overlaid portion of the upper at this time not only leaves the shoe of better shape around the toe so that the welt may set snugly when attached but also the inturned upper, by reason of its contraction or shrinking, has less tendency to slack back over the edge of the shoe when the wipers are withdrawn. If the heated wipers are allowed to remain over the upper long enough light upper material in some classes of work becomes so permanently formed that the shoe can be welted without binding in the toe. While I have described a preferred use of this invention, itis obvious that the apparatus may be used with or without heat and may be employed simply for lasting purposes without regard to the means employed for securing the upper. An adhesive coated toe binder which required simply to be moistened has been used with good results without heat and a binder, the adhesive of which is of proper quality, can be made to stick satisfactorily by pressure without the application of heat or moisture.
